This video looks at finding distances between line segments and how to find the midpoint of line segments. WIth a number of examples and backed up with a lot of theory, this video will answer all your questions about distance and midpoints.
This video continues the Methods 1 and 2 series for Coordinates and Linear Geometry. In this video I take a look at the following: Know the many forms we can write an equation of a straight line Gradient intercept form Intercept form Point gradient form Know how to find the equation of a line given certain conditions
This video looks at the theory behind finding the equations of straight lines. It's part of the Methods 1 and 2 course but relevant to all countries and Mathematics syllabi. It does this through using theory and examples. The main things covered in the lesson are: Know the many forms we can write an equation of a straight line Gradient intercept form Intercept form Point gradient form Know how to find the equation of a line given certain conditions
This video is your definitive guide to knowing how to graph straight lines. It relates to the Methods 1 and 2 course and deals with the following topics: Know how to use the various techniques used in previous lessons to sketch graphs of straight lines, including: * Intercept form * Gradient intercept form Know how to use your CAS to draw straight lines There are lots of worked examples and a discussion about the reasons why we do this. There are also lots of tips and tricks you can learn to make it easier!
This video continues the series for the Methods 1 and 2 textbook for Cambridge Essentials. Looking at parallel and perpendicular lines I spend time covering the following concepts: Know what makes lines parallel and perpendicular How to identify from equations if lines are parallel and perpendicular Know how to use the fact that lines are parallel and perpendicular to find equations This video will tell you all you need to know about Parallel and Perpendicular lines.
This video will show you everything you ever needed to know about families of straight lines. It's part of the Methods 1 and 2 course here in Australia, but it is equally valid for all maths courses the world over. The video deals with the following topics: Know what makes it means to have a family of straight lines Know the three families of straight lines which are used in the textbook series There are a number of worked examples provided to scaffold the theory and some useful exam hints and tips.
This video returns to look at Simultaneous equations for the Methods 1 and 2 course. Rather than looking at the ways of solving them, I show how to use techniques to see if there are zero, one or infinite solutions. This is done with a number of examples with the last example using Matrices to find the equations which have zero, one and infinite numbers of solutions. I show how equations can have zero, one and infinite solutions and exam tips and tricks.
